Prometheus .NET Serialization

C#damian
If you’ve ever used Prometheus or Prometheus-Net, you may have noticed that its Gauges use a JSON’ish implementation. And by “-ish” we mean that you cannot simply apply, System.Text.Json to deserialize the line. Here I’ll show you how to work with Prometheus to assist with your unit tests (aka automated tests, integration tests, etc). In this example, we’re going to extract the “Button Click” metrics sent by the app. Prometheus is an open-source systems monitoring solution to help collect metrics and alerts in your application. https://prometheus.io/docs/introduction/overview/ Below is an exert from the packet.

C# 9.0 Null Checking

C#damian
C# 9.0 added a lot of new features and enhanced others. Here we’re covering Pattern Matching, more specifically is null and is not null.  Beginning with C# 7.0, the “is” operator was added to match an expression against a pattern, and with C# 9.0 the negation pattern was added to do a non-null check. Overview So why not just use “==” or “!=” operators? When you override the operators, your traditional null checks can behave differently. This is why it can be safer for you to use the newer pattern matching. The addition of null checking using, “is null“, though…
